Commercial PAT Testing

Portable appliance testing keeps your equipment records current and provides evidence that electrical equipment is being appropriately maintained. We carry out PAT testing for commercial and public sector organisations across London and the South East, working around your operations to minimise disruption.

What is PAT testing and when do you need it?

Portable appliance testing is the inspection and testing of electrical equipment that has a plug. It can cover a wide range of equipment, from desktop computers and monitors to kettles, extension leads, power tools, and floor-standing equipment used in the workplace. Each item is visually inspected and electrically tested, and receives a clear pass or fail for continued use.

The Health and Safety at Work Act 1974 and the Electricity at Work Regulations 1989 require employers and duty holders to manage electrical risks and maintain electrical equipment so that it does not give rise to danger.

Testing frequency depends on the type of equipment and the environment it is used in: office equipment is typically tested every one to four years, while equipment used in higher-risk environments requires more frequent inspection.

What our PAT testing includes

We test every item within the agreed scope, working methodically through your site and recording the results.

Equipment is clearly labelled following inspection and testing, and any failed items are flagged immediately so appropriate action can be taken.

At the end of the visit you receive a complete electronic register of every item tested, with its serial number, location, test result, and any observations. That register is your compliance record.

Why Prolec

We work around you

Testing is planned around your hours of operation. For larger sites we can work in sections across multiple visits to avoid disruption.

Your register is accurate and complete

Equipment and test results are recorded systematically, giving you a useful audit trail and helping you manage future inspection and testing requirements

We flag failures on the day

Any item that fails is labelled and reported to you immediately so it can be taken out of use without delay.

Is PAT testing a legal requirement?

No fixed testing interval is set in law, but employers are required to maintain electrical equipment in a safe condition under the Health and Safety at Work Act 1974 and the Electricity at Work Regulations 1989. PAT testing carried out to the IET Code of Practice demonstrates that requirement has been met. Your insurer may also specify testing as a condition of cover.

How often does PAT testing need to be done?

Frequency depends on the type of equipment and the environment. Office equipment in low-risk settings is typically tested every one to four years. Equipment used in higher-risk environments, or by members of the public, should be tested more frequently. We can advise on the right schedule for your site.

What types of equipment need to be tested?

Any electrical equipment connected to the mains supply via a plug. That includes computers, monitors, printers, kitchen appliances, extension leads, chargers, power tools, and portable lighting. Fixed equipment, such as hard-wired appliances, is covered under your EICR rather than PAT testing.

What happens to items that fail?

Failed items are labelled with a fail sticker and reported to you on the day. They should be taken out of use until they have been repaired or replaced. We record all failures in your register with details of why the item failed.
